Arguments against humans being the reason for climate change. Misleading argument 1 : The Earth's climate is always
changing and this is nothing to do with humans. Misleading argument 2 : Carbon dioxide only makes up a small part of the atmosphere and so cannot be responsible for global warming. Misleading argument 3 : Rises in the levels of carbon dioxide in the atmosphere are the result of increased temperatures, not the other way round. Misleading argument 4 : Observations of temperatures taken by weather balloons and satellites do not support the theory of global warming.
Arguments (continued) Misleading argument 5 : Computer models which predict
the future climate are unreliable and based on a series of assumptions. Misleading argument 6 : It's all to do with the Sun - for example, there is a strong link between increased temperatures on Earth with the number of sunspots on the Sun. Misleading argument 7 : The climate is actually affected by cosmic rays. Misleading argument 8 : The scale of the negative effects of climate change is often overstated and there is no need for urgent action.
What are your thoughts? ď‚— The issue of global warming has been a major political
talking point for at least the last 10 years and it will continue with no obvious end. You need to be aware of the arguments and have your own opinions on the matter.
What are your thoughts and why?
Plenary – Attitude line Global Warming Humans are completel y to blame
Nature has the biggest effect
The Greenhouse Effect Using the information from the clip draw a diagram
that shows the ‘normal’ and positive Greenhouse Effect and then the ‘Human’ and detrimental Greenhouse Effect. Link to Global Warming Video Clip 2. YouTube - Al Gore Global Warming in 10 min 1.
Always remember the Greenhouse effect occurs
naturally!
How does global warming happen?

Human activity is creating more of these greenhouse gases so less heat is able to escape into space. This is causing the earth to warm up.
Heat from the sun passes through the earth’s atmosphere and warms the earth.
Make your own version of this labelled diagram
Some heat is reflected back from the earth into space. But some of the heat is trapped by greenhouse gases. These include water, vapour carbon dioxide and methane which occur naturally on earth and stop the earth getting too cold.
Watch the Global Warming Information Video in the folder.
Global Warming What are the main causes of global warming? Emissions from cars = CO2 Emissions from factories = Acid Rain Household waste = Not Biodegradable Industrial waste = Chemical waste harmful to nature Lack of recycling = Methane from landfills Why do we allow these things to continue? Transport of people and goods ‘Throwaway society’ Laziness
Effects of Global Warming Along with the obvious effect of a raise in temperature,
many other effects can be noted Smog from cars make it hard to breathe
Chemicals from factories create acid rain Household waste creates methane Factory waste can be chemical or radioactive and lasts
for many years in the soil and water of the local area.
